Dredging machinery muaj ib tug me me ntim thiab roj tank peev xwm, ua rau ib tug me me npaum li cas ntawm lubricating roj. Thaum lub sijhawm ua haujlwm, cov roj kub kub yog siab, xav tau cov roj lubricating kom muaj thermal stability thiab oxidation tsis kam.
Vim muaj qhov hnyav ntawm cov dej hauv dej, nrog cov ntsiab lus siab ntawm cov hmoov av, pob zeb hmoov av, thiab cov dej noo, cov roj lubricating yog inevitably paug los ntawm cov impurities. Yog li ntawd, cov roj lubricating rau suction dredgers yuav tsum muaj kev tiv thaiv xeb zoo, tiv thaiv corrosion, thiab tiv thaiv -emulsification zog; thiab nws qhov kev ua tau zoo yuav tsum tsis txhob hloov pauv loj thaum muaj kab mob, txhais tau tias nws yuav tsum muaj qhov tsis zoo rau kev sib kis.
Qhib-air machinery muaj qhov kub thiab txias hloov pauv ntawm lub caij ntuj sov thiab lub caij ntuj no, thiab qee thaj chaw kuj muaj qhov kub thiab txias sib txawv. Yog li ntawd, lub viscosity ntawm cov roj lubricating yuav tsum hloov me ntsis nrog kub. Nws yuav tsum tiv thaiv cov roj viscosity los ntawm qhov qis dhau ntawm qhov kub thiab txias, uas yuav tiv thaiv qhov tsim ntawm lubricating zaj duab xis thiab cuam tshuam rau lubrication kom zoo. Hloov pauv, nws tseem yuav tsum tiv thaiv kom tsis txhob muaj viscosity siab dhau ntawm qhov kub thiab txias, uas yuav ua rau pib thiab ua haujlwm nyuaj.
Rau qee lub tshuab dredging thiab cov cuab yeej siv (muaj xws li: tsav tsheb, khoom siv kis tau tus mob, thiab lwm yam), tshwj xeeb tshaj yog cov siv hauv cov mines uas muaj hluav taws kub nyhiab thiab kev sib tsoo yuav tshwm sim, cov roj nplua nyeem uas muaj hluav taws kub zoo (hluav taws- cov kua dej tiv thaiv) yuav tsum tsis txhob siv cov roj ntxhia hluav taws xob.
Lub lubricant yuav tsum muaj kev sib raug zoo nrog cov khoom sib khi los tiv thaiv kev puas tsuaj rau cov ntsaws ruaj ruaj.
